Designation:D622718An American National StandardStandard Specification forUnleaded Aviation Gasoline Containing a Non-hydrocarbonComponent1This standard is issued under the fixed designation D6227;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This specification covers Grades UL82 and UL87 un-leaded aviation gasolines,which are defined by this specifica-tion and are only for use in engines and associated aircraft thatare specifically approved by the engine and aircraftmanufacturers,and certified by the National Certifying Agen-cies to use these fuels.Components containing hetro-atoms(oxygenates)may be present within the limits specified.1.2 A fuel may be certified to meet this specification by aproducer as Grade UL82 or UL87 aviation gasoline only ifblended from component(s)approved for use in these grades ofaviation gasoline by the refiner(s)of such components,becauseonly the refiner(s)can attest to the component source andprocessing,absence of contamination,and the additives usedand their concentrations.Consequently,reclassifying of anyother product to Grade UL82 or Grade UL87 aviation gasolinedoes not meet this specification.1.3 Appendix X1 contains an explanation for the rationaleof the specification.Appendix X2 details the reasons for theindividual specification requirements.1.4 The values stated in SI units are to be regarded asstandard.The values given in parentheses after SI units areprovided for information only and are not considered standard.1.5 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D86 Test Method for Distillation of Petroleum Products andLiquid Fuels at Atmospheric PressureD130 Test Method for Corrosiveness to Copper from Petro-leum Products by Copper Strip TestD357 Method of Test for Knock Characteristics of MotorFuels Below 100 Octane Number by the Motor Method;Replaced by D 2700(Withdrawn 1969)3D381 Test Method for Gum Content in Fuels by Jet Evapo-rationD873 Test Method for Oxidation Stability of Aviation Fuels(Potential Residue Method)D909 Test Method for Supercharge Rating of Spark-IgnitionAviation GasolineD910 Specification for Leaded Aviation GasolinesD1266 Test Method for Sulfur in Petroleum Products(LampMethod)D1298 Test Method for Density,Relative Density,or APIGravity of Crude Petroleum and Liquid Petroleum Prod-ucts by Hydrometer MethodD2386 Test Method for Freezing Point of Aviation FuelsD2392 Test Method for Color of Dyed Aviation GasolinesD2622 Test Method for Sulfur in Petroleum Products byWavelength Dispersive X-ray Fluorescence SpectrometryD2699 Test Method for Research Octane Number of Spark-Ignition Engine FuelD2700 Test Method for Motor Octane Number of Spark-Ignition Engine FuelD3120 Test Method for Trace Quantities of Sulfur in LightLiquid Petroleum Hydrocarbons by Oxidative Microcou-lometry1This specification is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.J0.02 on Spark and Compression Ignition Aviation EngineFuels.Current edition approved Oct.1,2018.Published October 2018.Originallyapproved in 1998.Last previous edition approved in 2017 as D6227 17.DOI:10.1520/D6227-18.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3The last approved version of this historical standard is referenced onwww.astm.org.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 D3231 Test Method for Phosphorus in GasolineD3237 Test Method for Lead in Gasoline byAtomicAbsorp-tion SpectroscopyD3338 Test Method for Estimation of Net Heat of Combus-tion of Aviation FuelsD4052 Test Method for Density,Relative Density,and APIGravity of Liquids by Digital Density MeterD4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4171 Specification for Fuel System Icing InhibitorsD4294 Test Method for Sulfur in Petroleu
